By analop:y with Nymphaea alba - I a.ssume yon own my disserta- 
tlon^ (Appendix hört . bot. . berol 185^) (»•bei-ol«' = of Berlin, E,D.) - 
otht^T-wlse veT-y probable. I urfriently ask,to do the

morizes for declamation entire books of poems. She knows already 
verv many plants; all in Dreco* s picture books', We plan to have our 
iDicture taken in Summer-, then you shall .cret also a photop^raph of us 
all! - The mini stry^ appropriated more than 4,000 Thaler for the 
construction of a ma^nificent - the lärmest of all — Winter-plant 
house^n the local botanical p:arden..The construction was beficun last

late this year, to pret it finished-, to prrow already this year suc-

houses and in the open, also a pond; In it I have also Nuphar
